If you want to make your smile brighter, it's best to discuss it with your dentist, who will first clean your teeth and make sure, through a thorough examination, that you don't have cavities or defective restorations.
He or she will then be able to determine why your teeth are not as white as they used to be, a crucial step in the success of the treatment.
There are several possible causes of tooth discolouration.
First of all, your teeth may be covered with an accumulation of dental plaque and tartar. These deposits become discoloured if a person frequently drinks coffee, tea, red wine, or if they smoke.
A simple cleaning and polishing of the teeth is enough to remove superficial stains, but not when the staining is lodged in the enamel and dentin of the teeth.
Possible causes can be natural tooth aging, cavities, the consumption of tobacco products, certain medications, or too much fluoride at a young age.
Some people respond better to bleaching treatment than others.
Those with yellowish-tinged teeth usually respond better than those with brownish-tinged teeth.
Sometimes teeth can be greyish in colour. This is the result of taking tetracycline at a young age to treat certain childhood illnesses or taking minocycline used by teenagers and young adults to treat acne problems.
These stains are more resistant to bleaching and in some cases, unfortunately, it is not possible to eliminate them completely.
In addition, people whose front teeth have been restored with dental materials that have changed color over time will have to change them so that their teeth will have the same color.
The dentist isolates the teeth and protects the gums with a protective gel or rubber dam.
